| Spinal Lazer Surgery |  The principle of lasing phenomena is the ability of photons to provoke the expansion of other photons, besides each of them has the same wave length and direction of travel. When a photon comes up close to an excited electron, the electron will become stimulated to emit a photon that is identical in both wave length, phase and spatial coherence to the impinging photon.
Laser is often employed in Lazer Surgery for the Spine. It is a 2.1 Holmium YAG Laser. It is the most effective laser in orthopedic surgery and especially in arthroscopic and endoscopic surgery.
Lazer Surgery for the spine may be helpful in the following conditions:
Spinal Fusion
It is the surgical joining of two more vertebrae together, generally with bone grafts and hardware. The resulting fused vertebrae are stable but immobile. Spinal fusion is a treatment for spondylolisthesis, herniated discs, scoliosis, and spinal stenosis.
Spinal Stenosis
This is the narrowing of the spinal canal (through which the spinal cord runs), often by the overgrowth of bone caused by osteoarthritis of the spine.
Herniated Disc
With age, the center of vertebral discs begins to lose water content. This makes the disc less effective as a cushion and causes displacement of the disc’s center through a crack in the outer layer. Most disc herniations appears in the bottom two discs of the lumbar spine, at and just below the waist. A herniated disc can press on a nerve root in the spine and may provoke back pain, stupor, tingling or weakness of the leg called “sciatica.”
Degenerative Disc Disease
This term describes degenerative changes in the disc(s) due to aging or wear and tear.
Radiculopathy
Injury of a nerve root, which usually causes radiating pain, numbness, tingling or muscle weakness that correspond to a specific nerve root.
Sciatica
Pain, numbness, tingling in the distribution of the sciatic nerve, which travels from deep in the buttock down to the foot.
Spondylosis
This is a fracture in the “pars interarticularis” where the vertebral body and the posterior elements, protecting the nerves are joined. In about 5% of adults there is a developmental crack in one of the vertebrae, usually at the point at which the lower part of the spine joins the tailbone.
Spondylolisthesis Degenerative
This is a condition when a vertebra slides forward over the vertebra below it as a result of arthritis of the small joints of the spine and degeneration of the discs.
Spondylolisthesis Isthmic
This is a condition when a vertebra with a crack in the “pars interarticularis” where the vertebral body and the posterior elements, protecting the nerves are joined, sldes forward over the vertebra below it. Spondylolisthesis can be graded as I, II, III or IV based on how far forward the vertebra has slided.
